The preparation method has the advantages of simple preparation conditions, simplicity and convenience in operation, low cost, easiness in amplification and the like, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of functional materials, and more specifically relates to a flexible anti-corrosion tape and its preparation method and application. Background technique [0002] According to statistics, the economic loss caused by corrosion accounts for about 3% of GDP in the world every year, and the economic loss caused by steel structure corrosion is huge. The corroded steel structure not only affects the appearance, but also poses safety hazards, and may even cause equipment accidents and casualties. As common flanges, valves, bolts and other special-shaped components in steel structures, due to their complex structures, there are many defects, gaps and edges and corners, which are easy to accumulate water, moisture, salt, etc., and are prone to stress corrosion and galvanic corrosion. , Crevice corrosion and other corrosion behaviors, the corrosion problem of special-shaped parts is often more serious. Therefore, it...
